Product details
Overview
BZT5250H-C5V6-QX from Nexperia is a low-current Zener diode in SOD123F package, rated for 5.6 V nominal regulation at 50 µA test current, with ±5 % tolerance, 400 Ω differential resistance at 5 mA, and AEC-Q101 qualification for automotive use.
For engineers reviewing the BZT5250H-C5V6-QX datasheet, BZT5250H-C5V6-QX pinout, BZT5250H-C5V6-QX application, or BZT5250H-C5V6-QX equivalent, this device serves as a precision low-bias voltage reference in battery-powered sensor nodes, ECU power-rail monitoring, and automotive infotainment standby regulators where leakage-sensitive, stable clamping is required.
Technical Context
This Zener operates with a specified reverse breakdown voltage of 5.32 V (min) to 5.88 V (max) at IZ = 5 mA, exhibiting a temperature coefficient of –2.0 mV/K and diode capacitance of 120 pF at f = 1 MHz and VR = 0 V.
It delivers 830 mW total power dissipation on a 1 cm² cathode pad, with thermal resistance from junction to solder point at 70 K/W, and supports non-repetitive peak reverse power up to 40 W for 100 µs pulses.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 5.32 V to 5.88 V at IZ = 5 mA - defines tight regulation window for 5.6 V rail stabilization |
| Tolerance | ±5 % - enables cost-optimized selection for non-critical biasing without trimming |
| Differential Resistance (rdiff) | 400 Ω max at IZ = 5 mA - ensures stable voltage under small load variations |
| Test Current (IZ) | 50 µA - allows ultra-low quiescent current operation in always-on circuits |
| Forward Voltage (VF) | 0.9 V max at IF = 10 mA - minimizes forward conduction loss in dual-direction protection |
| Total Power Dissipation (Ptot) | 830 mW at Tamb ≤ 25 °C - supports compact PCB layout with minimal heatsinking |
| AEC-Q101 Qualified | Yes - validated for automotive-grade reliability including temperature cycling and HTRB |
Pinout & Package
SOD123F surface-mount plastic package: 2.6 mm × 1.6 mm × 1.1 mm body, flat lead, single-sided copper FR4 mounting, cathode marked by bar.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated output node; marking bar identifies this terminal for correct orientation |
| 2 | Anode (A) | Connected to ground or lower-potential rail; completes reverse-biased Zener path |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZT52-C5V6,115 | Same SOD123F package, ±5 % tolerance, but rated at 5 mA test current and higher rdiff (500 Ω) | Lacks AEC-Q101 qualification and optimized leakage profile for fast switching | Prefer for cost-sensitive industrial designs where automotive qualification is unnecessary |
| MMSZ5232BT1G | SOD-123 package, ±5 %, 5.6 V, but specified at 20 mA test current and higher Ptot (500 mW) | Higher forward voltage (1.1 V) and no AEC-Q101 validation; not suitable for low-IQ automotive use | Select only when higher surge handling is needed and leakage sensitivity is secondary |
Compared with BZT5250H-C5V6-QX, the BZT52-C5V6,115 offers identical form factor but lacks automotive qualification and low-leakage tuning, while MMSZ5232BT1G trades precision low-current operation for higher power capability-making the QX variant uniquely suited for AEC-Q101-compliant, battery-constrained systems.

FAQ
What is the maximum reverse voltage this Zener can sustain before breakdown?
The BZT5250H-C5V6-QX has a nominal Zener voltage of 5.6 V, with guaranteed breakdown between 5.32 V and 5.88 V at 5 mA. Its absolute maximum non-repetitive peak reverse voltage is defined by the 40 W surge rating at 100 µs pulse width, not a fixed VR(max); sustained reverse voltage must remain below the specified VZ window to avoid thermal runaway.
Is this device suitable for bidirectional ESD protection?
No - the BZT5250H-C5V6-QX is a unidirectional Zener diode optimized for reverse-biased regulation. Its forward voltage is 0.9 V max at 10 mA, but it lacks symmetric clamping characteristics or specified ESD ratings (e.g., IEC 61000-4-2). For bidirectional protection, dedicated TVS diodes like PESD5V0S1BA should be used instead.
How does the "C" suffix in BZT5250H-C5V6-QX affect its performance?
"C" denotes the ±5 % tolerance grade and indicates intentional minor leakage current optimization for faster switching and reduced noise, as documented in application note AN90031. This differs from "B"-grade parts (±2 %), which prioritize tighter voltage tolerance over dynamic response - making the "C" variant ideal for low-noise, low-IQ regulation.
Can this Zener operate reliably at 125 °C ambient temperature?
Yes - the device is rated for ambient temperatures from –55 °C to +150 °C and qualified to AEC-Q101. At 125 °C, derating applies: total power dissipation drops to approximately 420 mW (based on Rth(j-a) = 330 K/W and Tj(max) = 150 °C), requiring careful thermal design but remaining fully functional in under-hood automotive environments.
